Using the two column vectors A and B given below
A = %28matrix%282%2C1%2C-4%2C0%29%29 and B = %28matrix%282%2C1%2C-9%2C2%29%29,
find 3A + B
3A%22%22%2B%22%22B%22%22=%22%223%28matrix%282%2C1%2C-4%2C0%29%29%22%22%2B%22%22%28matrix%282%2C1%2C-9%2C2%29%29%22%22=%22%22%28matrix%282%2C1%2C3%2A%28-4%29%2C3%2A%280%29%29%29%22%22%2B%22%22%28matrix%282%2C1%2C-9%2C2%29%29%22%22=%22%22%28matrix%282%2C1%2C-12%2C0%29%29%22%22%2B%22%22%28matrix%282%2C1%2C-9%2C2%29%29%22%22=%22%22%28matrix%282%2C1%2C-21%2C2%29%29
